Late game permanent potion!
I think it would be a fien addition to the game.
Rarely, but sometime, game drag on for so long than you end up with full build, those 400 potion up...and yet have thousan gold spare you simply cannot use at all...
what about adding to the game possibility to buy ultra expensive potion than woudl give you permanent bonus stats...dunno, like 50 extra ad for a 3k gold....
just so you can still increase stats (even if technically nto cost effective) when you are jsust plain full build on a long long game -_-
